If you’re wondering what type of gas a STIHL backpack blower takes, the answer is pretty straightforward: you need to use a high-quality unleaded gasoline with an octane rating of at least 89. This ensures optimal performance and longevity for your blower. Additionally, it’s crucial to mix this gasoline with STIHL’s special 2-cycle engine oil at a ratio of 50:1. This combination keeps your engine running smoothly and efficiently.
Why the Right Gas Matters
Using the correct fuel is essential for several reasons:
Engine Performance
- Optimal Efficiency: High-octane fuel helps your engine perform at its best, reducing the risk of knocking or pinging.
- Longevity: Proper fuel mixtures can extend the life of your engine, saving you money in the long run.
Environmental Impact
- Reduced Emissions: Using high-quality fuel and oil can minimize harmful emissions, making your blower more environmentally friendly.
Maintenance
- Less Wear and Tear: The right fuel mix reduces the buildup of carbon deposits in your engine, which can lead to costly repairs down the line.
Mixing Fuel Correctly
Getting the mixture right is key. Here’s how to do it:
Steps to Mix Fuel
- Gather Materials: You’ll need unleaded gasoline and STIHL 2-cycle engine oil.
- Mixing Ratio: For every gallon (3.8 liters) of gasoline, add 2.6 ounces (75 ml) of oil.
- Shake Well: Make sure to shake the mixture thoroughly to ensure it’s well blended.
- Use Fresh Fuel: Always use fresh fuel; avoid using any mix that’s older than 60 days.
FAQ
What happens if I use regular gas instead of high-octane?
Using regular gas can lead to poor engine performance, knocking, and potential damage over time. It’s best to stick with high-octane unleaded gasoline.
Can I use synthetic oil instead of STIHL’s oil?
While you can use synthetic oil, it’s recommended to stick with STIHL’s specially formulated oil for the best results and to maintain warranty coverage.
How often should I change my fuel mixture?
You should prepare a fresh fuel mixture every 30 days or whenever you plan to use your blower. Old fuel can cause starting issues and performance problems.
Is it okay to store mixed fuel?
Yes, but only if it’s stored in a proper container designed for gasoline storage. Avoid keeping mixed fuel for longer than 60 days as it can degrade and harm your engine.
In summary, using the right type of gas and maintaining proper mixing practices are essential for keeping your STIHL backpack blower in top shape. Stick to high-quality unleaded gasoline mixed with STIHL’s 2-cycle oil, and you’ll be good to go!
